I have the very same problem
I would like to take out the resistor pack to check the terminals etc.
However, I cannot see how to get this out of the bulkhead
Haynes talks of removing one screw other literature two screws
I can see none on mine ( GP 2007)
I have pushed, squeezed this socket in all directions but it wont move

Any ideas

I tried and failed to remove it so I took a photo with the camera and had a look at it that way! I could see it was in perfect order so was happy to buy the replacement part knowing it would fit.

As promised, see the attached photos, they show it better. They show the new and old connector, cut down, burnt connector in comparison to the new one, new connector fitted, end result, it works a treat.

Brilliant thank you very much for your time and effort

Chinqster355 you're an absolute star...

I have had exactly the same problem with the heater in my daughter's GP and initially I simply wiggled the wires and connector block and the heater started working again.

However, since reading your thread I've investigated further and indeed both the plug and loom shows signs of burning.

So on your recommendation I've purchased a Corsa loom repair kit from eBay at a cost of £30 + £3.25pp (the photo and GM part number was identical to yours), so it should be an easy repair.

Just to point out that if anyone else goes looking for the repair loom it's titled 'CORSA D HEATER RESISTOR HARNESS REPAIR KIT'.

Thanks again, your photos and advice have been a great help. :slayer:

Hello there,

apologies for bringing an old thread back to life,

I need to get a new loom/resistor, how does the new loom "pack" fit into the existing wiring? On picture 5 above there are plastic "things" I assme the wiring goes into - do they come with the kit?

Thanks for any info

this any help?

Sort of, thanks.

I know I defin don't want to replace the whole loom now.. Got the parts lined up, but I'm just not sure what type of connectors to use when the wires are crimped?

Anyone got any idea what the ones above in the photos are? I've been to maplins today and they've got loads of different types..

Anyone know the wire thickness for example??

Thanks

To add to an old thread I have an mjet with climate control and air con. I may be being thick but I can't find this location in the place shown in pictures. Does anyone have a picture of where it would be on my car? The issue I have is that I can be set to full power and it'll turn itself down and back up over and over and gets annoying. I don't have it set to full auto mode either for the record so fully in my control??????

Plus now after being what appears to be a grade A tool since trying to clear out what turned out to be a clear motor my fan doesnt work at all. Could unplugging and replugging have blown a fuse? If so any help on a 1.9 mjet sporting 09 plate which fuse i need to check as the guide shows the S1 version location????? Help its bloody freezing!!! :bang:

KBonnie, I have the same issue with my 2006, 1.4 with climate control. The fan won't run at high speed for more than a second or so, and then turns itself back down. It keeps trying to get to full speed, but then goes back to slow.. Also I am not on full auto.

After a further look i have found that the gray plug of the two plugs going into the motor has a melted connector. Not sure if i can replace just that part will try and get a picture later but id start by looking there.

I just checked all 4 connectors that i can get to, and none of them show sign of overheating. I don't know if this is good or bad news for me

Hi sorry to bring this up.... im new to fiat puntos, i bought an 06 for my daughter and have the same fan problem. Ive checked all fuses, ihave power at the multiplug and have removed resister. Wires seem ok not burnt at all so am i right in thinking new resister will be the culprit ? Many thanks col.

Hi,

worth taking the fan out , and checking it actually runs with 12Volt supply to it's connector terminals

leaves/ parking tickets, etc can all build up and stop it..,

generally resistor problem fail to S L O W it, just runs at full chat permanently,

if it's NOT blowing , take it out,
3 screws..!!,

look in the Guides for info , GP , and similar Punto 2/b

Thanks charlie, it doesn't work at all on any speed, my daughter said it was making a noise like a piece of card in it. I will chexk in the morning. Do you know what pins out of the 5 is live and earth. Thanks

no problem,
did you figure out the issue,

Charlie

Yes i did thanks, brushes worn out in motor, i bought a new one from feebay.... fitted and cured the problem... very easy diy task to be honest. Cheers

I came across a quick fix to the overheated resistor pack plug on the Corsa forum where someone joined the orange & brown wires together in the loom bypassing the connector. This will make the fan run on full speed only via the fan control.
A bit more investigation shows that the orange & brown connectors (4&5) are actually joined on the resistor pack and even bypass the thermal fuse on the pack. I've attached the diagram from eLearn. The wiring colours and the speed switch wiring through the resistors is not correct at least so far as my 07 GP is concerned but the connectors are certainly joined together inside as per the diagram.
I've joined the brown & orange wires (4&5) in the loom just outside the connector, but left them also connected into the connector. Hopefully this will allow 2x the wires & connectors taking the load out of the pack to the motor for speeds 1-3 and will bypass the connector & pack altogether for top speed which is what puts the most load on the connector.
So far after a week, all is fine. But I take no responsibility if you try this, there maybe variations in the wiring colours or the actual wiring itself from time to time.

Thread resurrection! My heater does not work at all on any speed despite working perfectly 12 hours ago. I removed the motor thanks to the helpful guide, but there was no debris. I cannot get the resistor free (not for lack of trying). I did notice however my orange and brown look a little burnt? I'm no expert so looking for a second opinion before I decide what bit to buy (the Corsa D adapter kit or a new resistor).

From your description, I doubt if it's the motor brushes, but I may be wrong.

You could try joining the brown & orange wires on the wiring loom (leave some free wire above the connector) and then set the control to full speed. If this works, you can re-join the brown & orange back to the connector but leave them connected together as I did. I read somewhere about there being a screw holding the resistor pack in place, maybe that's why it won't move sideways?
An alternative is to buy a new wiring connector and a new resistor pack, then cut & join all the wires to the new connector.

As I noted in my first post, I can't take any responsibility for anything you do to your own wiring, but this did work for me and was fine 18 months later.
